 * negative. They are called the sessionId and the commandId resp..
 * The third mandatory token is the name of the communication partner who
 * initiated the session. The last/(4th) mandatory token is the request command.
 * All subsequent tokens are called request arguments. The number and type of
 * the request arguments are determined by the type of the request command.
